While in theory you can call an aquarium with dead fish and algae “in use” and tell your neighbors that you have fish and have a green thumb, it wouldn’t be necessarily an accurate assessment of the situation. Similarly, an occasional user that tries things doesn’t make those experimental RRTYPEs to be “in use”.
